Prox Velocity Stack
The OEM throttle bodies for the latest fuel injected MX bikes are mainly designed for higher RPM horsepower. However, this is not the best set up for all riding conditions and tracks. Therefore we like to introduce the ProX Velocity Stack. The Velocity Stack has the following advantages:
Faster and smoother throttle response.
Improves power on low RPM
Easy installation without remapping the ECU
Manufactured in light weight aluminum with high quality finish
